A cup of honey is verrrrry sweet! (Also, in ayurveda, honey is never supposed to be cooked as it turns into a toxin - and instead the raw honey is used in interesting ways - anyway, I digress). However, a cup of intense sweetness divided up into dense almonds and eggs probably disperses well.
It’s worth experimenting with - maybe a half cup erythritol and a full cup xylitol??? Ideally, pure monk fruit (not all the brands that say they’re monk fruit but only add a tiny bit to what is basically an erythritol sweetener etc), but that stuff is expensive - a cup of it will cost you arouns 8-10 bucks!
I bet there are folks here who are experts on mixing stevia with other keto friendly sweeteners in ways that heighten the sweetness but don’t overpower.
Hope you can experiment and report back!!! Maybe just do half-recipe little cakes till you figure out the perfect alchemy…
There are times when a wonderful keto friendly cake can celebrate so much!
